13.8 Transformations Review - II

A transformation is an operation that moves or changes a geometric figure in some way to produce a new figure. The new figure is called the image. Another name for the original figure is preimage.

A transformation can be shown using an arrow.
DABC ® DPQR

Three main types of transformations:

  • Translation moves every point of a figure the same distance in the same direction.

  • Reflection uses a line of reflection to create a mirror image of the original figure.
  • Rotation turns a figure about a fixed point, called the center of rotation . Rays drawn from the center of rotation to a point and its image form the angle of rotation.
Translations, reflections and rotations are three types of congruence transformations. A congruence transformation changes the position of the figure without changing its shape and size.
Another name for congruence transformation is isometry. An isometry is a transformation that preserves length and angle measure.

Dilation

  • A dilation is a transformation that stretches or shrinks a figure to create a similar figure.
  • It is a type of similarity transformation.
  • In a dilation, a figure is enlarged or reduced with respect to a fixed point called the center of dilation.
  • The scale factor of the dilation is the ratio of a side length of the image to the corresponding side length of the original figure.
